At 0003 March 31, 1993, the USCG MSO Philadelphia was notified by Tioga Marine Terminal
of an acetone-like odor in the area.
There were partly cloudy skies, winds east 5 to 10 knots,
with a temperature of 60F at the time of the incident.
MSO personnel estimated that between 32,000 to 600,000 gallons of cumene
had been released from the M/V Ellen Knutsen into the Delaware River.
The 442-foot Ellen Knutsen was docked at the GATX terminal in Port Richmond, PA
just south of the Betsy Ross Bridge on the Delaware River.
The source of the release was a two-inch crack
between the #5 starboard segregated ballast tank and the #10S cargo tank
that permitted cargo to leak into the adjacent ballast tank.
The ballast-cumene mixture discharged into the Delaware River during deballasting.
The spill spread as far downstream as Camden, NJ and upstream to near the Tacony-Palmyra Bridge.
GATX personnel stopped transfer operations as soon as the spill was discovered.
The total estimated release was 16,000 gallons.

Guessing fatigue.
This was a spill in which double hull hurt.
